Description
Overview
GAOTek pressure anemometer is to put a thin metal wire in the fluid, and the electric current heats the metal wire, making its temperature higher than the temperature of the fluid, so the wire anemometer is called “hot wire”. When the fluid flows through the wire in the vertical direction, it will take away part of the heat of the wire, making the temperature of the wire drop. According to the forced convective heat exchange theory, it can be deduced that there is a relationship between the heat lost by the hot wire Q and the velocity V of the fluid.
